SECTION 6
Place the header bracket on the
wall as shown in Figure 48.
Ensure that the bottom edge of
the bracket is level, and between
20mm - 50mm, but no more than
50mm above the highest arcing
point of the garage door. Mark the
location of the three screw holes
(Hole A, B, C and D[optional]).
Note the orientation of the
header bracket.
Mounting the drive rail
more than 50mm above
the highest arcing point
of the garage door may
cause the drive rail to
flex excessively.
Drill four 11mm diameter holes in
position of 'Hole A', 'Hole B', 'Hole
C' and 'Hole D'(optional), at least
50mm deep.
Place a fischer plug in each hole,
followed by the header bracket.
Secure it in position with at least
three coach screws (supplied)
(13mm hexagonal head).
